<p>
 Computes summary statistics for a stream of data values added using the
 <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/SummaryStatistics.html#addValue(double)"><CODE>addValue</CODE></A> method. The data values are not stored in
 memory, so this class can be used to compute statistics for very large data
 streams.
 </p>
 <p>
 The <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/StorelessUnivariateStatistic.html" title="interface in org.apache.commons.math3.stat.descriptive"><CODE>StorelessUnivariateStatistic</CODE></A> instances used to maintain summary
 state and compute statistics are configurable via setters. For example, the
 default implementation for the variance can be overridden by calling
 <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/SummaryStatistics.html#setVarianceImpl(org.apache.commons.math3.stat.descriptive.StorelessUnivariateStatistic)"><CODE>setVarianceImpl(StorelessUnivariateStatistic)</CODE></A>. Actual parameters to
 these methods must implement the <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/StorelessUnivariateStatistic.html" title="interface in org.apache.commons.math3.stat.descriptive"><CODE>StorelessUnivariateStatistic</CODE></A>
 interface and configuration must be completed before <code>addValue</code>
 is called. No configuration is necessary to use the default, commons-math
 provided implementations.
 </p>
 <p>
 Note: This class is not thread-safe. Use
 <A HREF="../../../../../../org/apache/commons/math3/stat/descriptive/SynchronizedSummaryStatistics.html" title="class in org.apache.commons.math3.stat.descriptive"><CODE>SynchronizedSummaryStatistics</CODE></A> if concurrent access from multiple
 threads is required.
